Bored and sex-deprived, I find myself in a precarious situation. My step-mom and step-sister, both gorgeous and horny as hell, catch me struggling with my raging boner. They exchange a look, then a wicked smile. "We can help with that," my step-mom purrs, her eyes locked on my tented shorts. My step-sister, a teen babe with a hungry look, nods in agreement. They strip, revealing their luscious bodies, and begin to tease me mercilessly. I'm a virgin, but they're determined to change that.
